[0023] The above-described embodiments of the present disclosure have the following beneficial effects: Through the three-dimensional search content display method of some embodiments of the present disclosure, the compatibility of the displayed search content with AR devices is improved, and the stereoscopic and spatial perception when viewed by the user is enhanced. Specifically, the poor compatibility of the displayed search content with AR devices and the poor stereoscopic and spatial perception when viewed by the user are caused by the tiled display method being the same as the display method in two-dimensional applications, resulting in poor compatibility of the displayed search content with AR devices and poor stereoscopic and spatial perception when viewed by the user. Based on this, the three-dimensional search content display method of some embodiments of the present disclosure first obtains a search content sequence based on input information of a search box displayed in the corresponding three-dimensional space or the current user's preference information. The search content sequence includes N search contents, each of which is sorted by information popularity. Thus, the search contents can be obtained, sorted by popularity, based on the user's input information or user's preference information. Then, based on the sequence order n (1<=n<=N, an integer) of each search content in the search content sequence, display location information for each search content is generated. Among them, the display location information in the above-mentioned each display location information includes a horizontal coordinate X, a vertical coordinate Y, and a depth coordinate Z. The horizontal coordinate X represents the horizontal order relative to the camera position. The vertical coordinate Y represents the longitudinal order of a column corresponding to the horizontal coordinate X. The depth coordinate Z represents the depth order relative to the camera position. Therefore, the display location information of each search content can be determined according to the popularity order of each search content. The display location information includes the horizontal coordinate X, the vertical coordinate Y, and the depth coordinate Z, which can indicate that the display location information is three-dimensional. Then, according to the horizontal coordinate X, the vertical coordinate Y and the depth coordinate Z corresponding to each search content, the search content cards corresponding to the above-mentioned each search content are displayed in the above-mentioned three-dimensional space. Among them, the search content card displays the homepage content information of the corresponding search content. According to the order in the search content sequence, the above-mentioned search content card is displayed in the three-dimensional display layer corresponding to the depth coordinate corresponding to the search content. In each three-dimensional display layer of the above-mentioned three-dimensional space, each search content corresponding to each search content card corresponding to the field of view angle area is arranged at the front end of the above-mentioned search content sequence, and the display brightness of the three-dimensional display layer farther away from the camera position is smaller than the display brightness of the three-dimensional display layer closer to the camera position. The above-mentioned search content cards have the same horizontal width. Therefore, the three-dimensional display position information can be used to display each search content in different levels in the form of cards in the three-dimensional space, and the search content with higher popularity can be displayed in the form of cards in the field of view angle area. The displayed search content cards have the same horizontal width, which can make the search content cards neatly arranged for easy viewing by the wearer.The 3D display layers closer to the camera have a higher display brightness, making it easier for the wearer to view the content displayed in the 3D display layer in front. Finally, in response to detecting a slide-to-refresh operation on each 3D display layer in the 3D space, updated search content cards are displayed in each 3D display layer. The 3D space is displayed in an AR device with a FOV range of 40-60 degrees. The value of N ranges from 11 to 55. The value of the horizontal coordinate X ranges from -5 to 5. The value of the depth coordinate Z ranges from 1 to 4. Thus, the search content cards displayed in each 3D display layer in the 3D space can be refreshed overall. Because the displayed search content cards are displayed in different 3D display layers at different distances from the camera and at different display brightnesses, the integration with the AR device's functions is enhanced, thereby improving the compatibility of the displayed search content with the AR device. Furthermore, because the displayed search content cards correspond to different depths and brightnesses, the wearer's sense of three-dimensionality and spatial perception is enhanced when viewing each search content card. As a result, the compatibility of the displayed search content with the AR device is improved, and the stereoscopic and spatial perception of the wearing user is enhanced.

[0036] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0037] FIG1 shows a process 100 of some embodiments of a method for displaying search content in a three-dimensional space according to the present disclosure. The method for displaying search content in a three-dimensional space includes the following steps:

[0038] Step 101: Acquire a search content sequence according to input information of a search box displayed in a corresponding three-dimensional space or preference information of a current user.

[0039] In some embodiments, the execution entity (e.g., an AR device) of the method for displaying search content in a three-dimensional space may obtain a search content sequence from a server via a wired or wireless connection based on input information in a search box displayed in the corresponding three-dimensional space or the current user's preferences. The three-dimensional space may be a space with depth properties that is integrated with the real world. The search box may be a box for entering information to be searched. The input information may be information confirming the search. For example, the input information may be text entered via a keyboard. The input information may also be voice or text entered via voice. In another example, the input information may be an image. The current user may be a user wearing the AR device. The preference information may be pre-configured information representing user preferences. For example, the preference information may include, but is not limited to, preferred news types and preferred information presentation methods (video, image, text). The search content sequence may be various items of content retrieved based on the input information or preference information. The content types of the individual search items in the search content sequence may include, but are not limited to, video, image, and text. Optionally, the video category may be specifically categorized as horizontal video or vertical video. For example, the video ratio of the horizontal video category may be 16:9. The video ratio of vertical videos can be 9:16. The search content sequence can include N search contents, where each search content is sorted by information popularity. For example, information popularity can be determined based on the initial popularity of the information, the interactive popularity of the information, and the popularity that decreases over time. The search contents in the search content sequence can be sorted in descending order of information popularity.

[0040] It should be noted that the above-mentioned wireless connection methods may include but are not limited to 3G / 4G connection, WiFi connection, Bluetooth connection, WiMAX connection, Zigbee connection, UWB (ultra wideband) connection, and other wireless connection methods currently known or to be developed in the future.

[0041] Step 102 : Generate display position information of each search content according to the sequence order n (1<=n<=N, an integer) of each search content in the search content sequence.

[0042] In some embodiments, the execution entity may generate the display location information for each search content based on the sequence order n (1 <= n <= N, an integer) of each search content in the search content sequence. In practice, the execution entity may sequentially arrange the search content from top to bottom and to both sides starting from the initial horizontal coordinate to obtain the horizontal and vertical coordinates of each search content. The size of the area corresponding to each search content may be the same or may vary depending on the content type. The initial horizontal coordinate may correspond to the first position at the top center of the field of view area. The horizontal coordinate X represents the horizontal order relative to the camera position, and the vertical coordinate Y represents the vertical order of the column corresponding to the horizontal coordinate X. The horizontal coordinate to the left of the initial horizontal coordinate may be negative. The horizontal coordinate to the right of the initial horizontal coordinate may be positive. The initial vertical coordinate may be the first position at the top center of the field of view area. The vertical coordinate may be positive. Vertically downward may be in the positive direction. The search content may then be sequentially divided into three-dimensional display layers in the three-dimensional space. The division may be performed in a round-robin manner. For example, the three-dimensional space may include four three-dimensional display layers. The execution entity may divide the first search content into the first three-dimensional display layer, the second search content into the second three-dimensional display layer, the third search content into the third three-dimensional display layer, the fourth search content into the fourth three-dimensional display layer, the fifth search content into the first three-dimensional display layer, and so on. Next, the order of the three-dimensional display layers corresponding to each search content may be determined as depth coordinates, and the horizontal coordinates, vertical coordinates, and depth coordinates corresponding to the search content may be determined as the display position information of the search content. The depth coordinate Z represents the depth order relative to the camera position. The larger the depth coordinate, the farther the distance from the camera position.

[0043] Optionally, any three-dimensional display layer in the above three-dimensional space corresponds to a pre-divided card display column sequence. The above card display column sequence is arranged in increasing counterclockwise order from the center position. For example, the central axis of the field of view can be the middle column, that is, the first column. The right side can be an even column (column 2, column 4, column 6, column 8, column 10). The left side can be an odd column (column 3, column 5, column 7, column 9, column 11). The number of search content cards that can be displayed in each card display column is less than a preset number. For example, the preset number can be 4. Optionally, the total height of the search content cards that can be displayed in each card display column and the intervals between cards can be less than the preset height. For example, the preset height can be 1270px.

[0044] In some optional implementations of some embodiments, the execution entity may generate the display location information of each of the search contents through the following steps:

[0045] The first step is to determine the card size corresponding to the search content according to the content type corresponding to each search content in the search content sequence. The card widths included in the determined card sizes are the same. In practice, the card size corresponding to each content type can be pre-set. For example, the card size corresponding to the video category can be the card size with a video first picture ratio of 9:16 (vertical video) or 16:9 (horizontal video). The card size with a video first picture ratio of 9:16 can be 320px: (569px+100px), where 320px can be the card width, 569px can be the height of the cropped video first picture, and 100px can be the height of the search content title. The card size with a video first picture ratio of 16:9 can be 320px: (180px+100px). 180px can be the height of the cropped video first picture, and 100px can be the height of the search content title. The card size for graphics or text can be 320px: (240px + 100px), where 240px is the height of the cropped first image or text box. The cropped first image or text box can have a 4:3 ratio.

[0046] In the second step, the first card display column in the above card display column sequence is determined as the current card display column.

[0047] The third step is to determine the first search content in the search content sequence as the current search content.

[0048] Step 4: Based on the current card display column and the current search content, execute the following loop steps:

[0049] In a first sub-step, in response to determining that the remaining display size of the current card display column is larger than the card size corresponding to the current search content, and the number of search content items to be displayed corresponding to the current card display column is less than the difference between the preset number and the preset value, the horizontal and vertical coordinates corresponding to the current search content are determined based on the initial vertical coordinate of the current card display column or the vertical coordinate corresponding to the last search content to be displayed, and the search content following the current search content is used as the current search content, and the above-mentioned loop steps are executed again. The remaining display size may be the size of the remaining space available for arranging cards in the current card display column. The search content items to be displayed corresponding to the current card display column may be the search content items determined to be arranged in the current card display column. The initial vertical coordinate corresponding to the first card display column may be at the top, i.e., 1. The initial vertical coordinate corresponding to the second card display column may be at the bottom, i.e., a preset number of 4. The initial vertical coordinate corresponding to the third card display column may be at the top, i.e., 1. It is understood that the search content items can be arranged counterclockwise in each card display column. In practice, the above-mentioned execution entity may, in response to determining that the current card display column does not correspond to the search content, determine the horizontal coordinate of the current search content as the column number corresponding to the current card display column, and determine the initial vertical coordinate corresponding to the current card display column as the vertical coordinate of the current search content. The above-mentioned execution entity may also, in response to determining that the current card display column corresponds to the search content, determine the last search content corresponding to the current card display column as the previous search content. Then, in response to the initial vertical coordinate corresponding to the current card display column being at the top, the next vertical coordinate of the vertical coordinate corresponding to the previous search content may be determined as the vertical coordinate of the current search content. In response to the initial vertical coordinate corresponding to the current card display column being at the bottom, the previous vertical coordinate of the vertical coordinate corresponding to the previous search content may be determined as the vertical coordinate of the current search content.

[0050] In the second sub-step, in response to determining that the remaining display size of the current card display column is larger than the card size corresponding to the current search content, or the number of search content to be displayed corresponding to the current card display column is less than the difference between the preset number and the preset value, the card display column next to the current card display column is used as the current card display column, and the above loop steps are executed again. In this way, the two-dimensional arrangement coordinates of each search content can be determined based on the information popularity order of the search content, the card size, and the arrangement order of each card display column.

[0051] Step 5: For each search content in the above search content sequence, perform the following steps:

[0052] In a first sub-step, in response to determining that the serial number of the search content satisfies a first preset divisibility condition corresponding to a first value, the first value is determined as the depth coordinate corresponding to the search content. The first value may be 2. The first preset divisibility condition may be that the serial number is divisible by 2 but not by 3.

[0053] In a second sub-step, in response to determining that the serial number of the search content satisfies a second preset divisibility condition corresponding to a second value, the second value is determined as the depth coordinate corresponding to the search content. The second value may be 3. The second preset divisibility condition may be that the serial number is divisible by 3.

[0054] In a third sub-step, in response to determining that the sequence number of the search content does not satisfy the first and second preset divisibility conditions, a third value is determined as the depth coordinate corresponding to the search content. The second value is greater than the first value, and the first value is greater than the third value. The third value may be 1.

[0055] The fourth sub-step is to determine the horizontal coordinates, vertical coordinates, and depth coordinates corresponding to the search content as display location information corresponding to the search content. In this way, the three-dimensional coordinates of the search content can be determined according to the order of information popularity of the search content.

[0056] As an example, a schematic diagram of arranging search content can refer to Figure 2. In Figure 2, the card display column sequence can be divided into 11 columns. The middle column is the first column. The left side is the odd-numbered column. The right side is the even-numbered column. There are 39 search contents in total. The smaller the serial number, the higher the information popularity. Search contents with smaller serial numbers are prioritized in the middle position. The search contents in the first column are arranged from top to bottom from the field of view area, and the first search content is aligned with the top edge of the field of view area. The search contents in the second column are arranged from bottom to top from the field of view area, and the last search content is aligned with the top edge of the field of view area. The search contents in the third column are arranged from top to bottom from the field of view area, and the last search content is aligned with the bottom edge of the field of view area. The search content is divided into three different three-dimensional display layers.

[0057] Optionally, for each search content in the above-mentioned search content sequence, the above-mentioned execution entity may determine the depth coordinate of each search content according to a preset hierarchical arrangement order. For example, the hierarchical arrangement order may be "1, 2, 3, 2, 1, 3". For example, the depth coordinate of the first search content may be 1. The depth coordinate of the second search content may be 2. The depth coordinate of the third search content may be 3. The depth coordinate of the fourth search content may be 2. The depth coordinate of the fifth search content may be 1. The depth coordinate of the sixth search content may be 3. The depth coordinate of the seventh search content may be 1. The depth coordinates of each search content may be determined in such a sequential cycle.

[0058] Step 103 : Displaying search content cards corresponding to the search content in the three-dimensional space according to the horizontal coordinate X, vertical coordinate Y, and depth coordinate Z corresponding to the search content.

[0059] In some embodiments, the execution entity may display search content cards corresponding to the search content in the three-dimensional space based on the horizontal coordinate X, vertical coordinate Y, and depth coordinate Z corresponding to each search content. The search content cards display the homepage content information of the corresponding search content. The homepage content information may be information for users to review in advance. Specifically, for search content cards for video content, the homepage content information may include a cropped video header image and a string from the search content title that can fit within a preset title size. For search content cards for graphic and text content, the homepage content information may include a cropped main image and a string from the search content title that can fit within a preset title size. For search content cards for text content, the homepage content information may include a text box of a preset size and a string from the search content title that can fit within a preset title size. The text box may display a brief summary of the search content. Brief content not displayed due to text box size limitations may be indicated by an ellipsis. The preset sizes and title sizes may be the same or different. Based on the order of the search content sequence, the search content cards are displayed in the three-dimensional display layer corresponding to the depth coordinates of the search content. In each three-dimensional display layer of the three-dimensional space, the search content corresponding to each search content card in the corresponding field of view area is arranged at the front of the search content sequence. This allows the wearer to view the most popular search content cards from a normal viewing angle. The display brightness of three-dimensional display layers farther from the camera position is lower than that of three-dimensional display layers closer to the camera position. For example, the brightness of the first three-dimensional display layer can be 1 (normal brightness), the brightness of the second three-dimensional display layer can be 0.7 (30% brightness reduction), and the brightness of the third three-dimensional display layer can be 0.4 (60% brightness reduction). This allows the wearer to better view the search content cards in the front three-dimensional display layer. The search content cards have the same horizontal width, which ensures a more regular arrangement of the search content cards.

[0060] In practice, for each search content, the execution entity can determine the display position and three-dimensional display layer of the search content card according to the horizontal coordinate X, vertical coordinate Y, and depth coordinate Z corresponding to the search content. Then, the preset search content card template can be displayed at the above display position in the three-dimensional display layer, and the homepage content information corresponding to the above search content can be displayed in the above search content card template. Here, the display position can be a three-dimensional coordinate position mapped to a three-dimensional coordinate system. The search content card template can be a blank card template. The edge of the search content card template can be covered with a shadow with thickness. For example, the edge of the search content card template can present a transparent luminous glass shadow with thickness. The card size corresponding to each search content card template can be the same, or it can vary with the content type.

[0061] Optionally, the search content card may include a main area and a sub-area. For search content cards with video content, the main area may be used to display the video first image, and the video first image displayed in the search content card may also display a video play icon, and the sub-area may be used to display the search content title. For search content cards with text content, the main area may be used to display the main image, and the sub-area may be used to display the search content title. For search content cards with text content, the main area may be used to display a text box, and the text box displayed in the search content card may also display an icon of the text source application, and the sub-area may be used to display the search content title. It is understandable that, due to the area size limitation, the search content title displayed in the sub-area may be a partial character string, and the remaining character string may be represented by ellipsis.

[0062] Optionally, each search content card corresponding to the first card display column can be moved as a whole to the top edge of the field of view angle area, that is, the top of the first search content card is aligned with the top edge of the field of view angle area. Each search content card corresponding to the second and third card display columns can be moved as a whole to the bottom edge of the field of view angle area, that is, the bottom of the last search content card is aligned with the bottom edge of the field of view angle area. Each search content card corresponding to the fourth and fifth card display columns can be moved as a whole to the top edge of the field of view angle area, that is, the top of the first search content card is aligned with the top edge of the field of view angle area. It is understandable that the alignment direction of the card display column in which the search content card needs to overlap with the top or bottom edge of the field of view angle area begins to reverse every time it reaches an even-numbered column. It is understandable that the alignment direction begins to reverse every time it reaches an even-numbered column, which can make the distribution of the arranged search content cards in space more balanced.

[0063] Step 104 : In response to detecting a slide refresh operation on each three-dimensional display layer in the three-dimensional space, display updated search content cards in each three-dimensional display layer.

[0064] In some embodiments, the execution entity may display updated search content cards in each of the three-dimensional display layers in response to detecting a sliding refresh operation for each of the three-dimensional display layers in the three-dimensional space. The sliding refresh operation may be a left-slide operation acting on the entire three-dimensional space. Here, the left-slide operation may be determined by identifying a user gesture. For example, a left-slide operation may correspond to a gesture of waving to the left. The search content corresponding to each updated search content card may be the search content corresponding to the input information or the preference information, and the corresponding information heat is less than the search content in the search content sequence. In practice, the manner in which the execution entity displays updated search content cards in each of the three-dimensional display layers may refer to steps 102-103, which will not be described in detail here.

[0065] It should be noted that the above-mentioned three-dimensional space can be displayed in an AR device with a FOV range of 40-60 degrees. The value range of N is 11 to 55. Here, displaying a total of 11 to 55 search content cards in the three-dimensional space can be a number range determined according to the FOV size for easy observation by the user. The value range of the horizontal coordinate X is -5 to 5. Here, the value range of the horizontal coordinate X is -5 to 5, which can indicate that a maximum of 11 columns of search content cards can be displayed in the three-dimensional space, and the other 5 columns are distributed on both sides of the middle column. Displaying a maximum of 11 columns of search content cards in the three-dimensional space can be a number range determined according to the FOV size for easy observation by the user. The value range of the depth coordinate Z is 1 to 4. The value range of the depth coordinate Z is 1 to 4, which can indicate that a maximum of 4 three-dimensional display layers for displaying search content cards can be displayed in the three-dimensional space. Displaying a maximum of 4 three-dimensional display layers in the three-dimensional space can be a number range determined according to the user's perception of spatial hierarchy. Too many layers will lead to confusion in the spatial content.

[0066] Optionally, the value of Z can range from 1 to 3. Displaying a maximum of three 3D display layers in a 3D space can be a number range determined based on the user's ability to perceive spatial hierarchy, which can further reduce the clutter of spatial content in the 3D space. When n is divisible by 3, Z = 3. When n is not divisible by 3 but divisible by 2, Z = 2. When n is neither divisible by 3 nor by 2, Z = 1. This allows the search content that is ranked first to be allocated to the 3D display layer that is closer to the camera position as much as possible.

[0067] Optionally, the execution entity may also respond to detecting a sliding back operation on each three-dimensional display layer in the three-dimensional space, and each three-dimensional display layer currently displays updated search content cards. For each three-dimensional display layer, the execution entity may display the search content cards that were last displayed in the three-dimensional display layer. The sliding back operation may be an operation to return to the previous state display. For example, the sliding back operation may be a right swipe operation. Here, the right swipe operation may be determined by identifying a user gesture. For example, the right swipe operation may correspond to a gesture of waving to the right. Thus, the user may view the historical display content in the three-dimensional space through gesture operations. It is understandable that the number of sliding back operations may be set to be less than or equal to a preset number, thereby allowing the user to view a limited number of historical display contents.

[0068] Optionally, the edges of each search content card are also displayed on both sides of the viewing angle area. The display brightness of each search content card edge portion is smaller than the display brightness of the three-dimensional display layer corresponding to the search content card edge portion. For example, the display brightness of the search content card edge portion can be reduced by 40% compared to the display brightness of the three-dimensional display layer in which it is located.

[0069] As an example, the three-dimensional display layers in the three-dimensional space can refer to Figure 3. In Figure 3, the search content cards are arranged in three layers, including three-dimensional display layer 301, three-dimensional display layer 302 and three-dimensional display layer 303. The display brightness of each layer is different, and the display brightness of the three-dimensional display layer closer to the camera position is higher. The higher the display brightness, the brighter the displayed content. The displayed search content cards can refer to Figure 4. Figure 4 can be used to display the display content in the three-dimensional space viewed by the user with a straight line of sight. The field of view area 401 can display a complete five columns of search content cards. The user can turn their head to view the other three columns of search content cards on both sides. The edge parts of each search content card are also displayed on both sides of the field of view area 401, including the edge parts of each search content card on the left and the edge parts of each search content card on the right.

[0070] Optionally, the execution entity may also, in response to detecting a field of view angle movement operation in the three-dimensional space, display each search content card in the updated field of view angle area corresponding to the field of view angle movement operation, and for each search content card edge portion on the side of the field of view angle area corresponding to the field of view angle movement operation, update the display brightness of the edge portion of the search content card to the display brightness of the three-dimensional display layer corresponding to the edge portion of the search content card. The field of view angle movement operation may be an operation in which the user turns their head to look at another area, and the field of view angle may move accordingly, thereby updating the field of view angle area. Thus, when the user looks at the area where the edge portion of the search content card is located, the display brightness of the edge portion of the search content card can be restored to the display brightness of the originally set three-dimensional display layer.

[0071] As an example, if the user turns their head left in the three-dimensional space corresponding to Figure 4, the search content cards displayed in the three-dimensional space can be referred to in Figure 5. Figure 5 can display the remaining three columns of search content cards on the left side, and the edges of the search content cards that had reduced display brightness in Figure 4 can be restored to the display brightness of their corresponding three-dimensional display layer in Figure 5.

[0072] Optionally, in response to detecting a hover operation on a search content card displayed in any three-dimensional display layer, the execution entity may enlarge and display a target search content card in the aforementioned three-dimensional display layer. The target search content card is the search content card corresponding to the hover operation. The size of the sub-area for displaying the search content title in the enlarged target search content card is larger than the original size of the sub-area. If the content type corresponding to the target search content card is video, the enlarged target search content card can automatically loop the video. If the content type corresponding to the target search content card is graphic or text, the size of the main area in the enlarged target search content card is larger than the original size, allowing for image magnification. If the content type corresponding to the target search content card is graphic or text, the content displayed in the enlarged target search content card supports page flipping. In practice, the target search content card can be enlarged proportionally by a predetermined multiple. For example, the predetermined multiple can be 1.3 times.

[0073] The above-described embodiments of the present disclosure have the following beneficial effects: Through the three-dimensional search content display method of some embodiments of the present disclosure, the compatibility of the displayed search content with AR devices is improved, and the stereoscopic and spatial perception when viewed by the user is enhanced. Specifically, the poor compatibility of the displayed search content with AR devices and the poor stereoscopic and spatial perception when viewed by the user are caused by the tiled display method being the same as the display method in two-dimensional applications, resulting in poor compatibility of the displayed search content with AR devices and poor stereoscopic and spatial perception when viewed by the user. Based on this, the three-dimensional search content display method of some embodiments of the present disclosure first obtains a search content sequence based on input information of a search box displayed in the corresponding three-dimensional space or the current user's preference information. The search content sequence includes N search contents, each of which is sorted by information popularity. Thus, the search contents can be obtained, sorted by popularity, based on the user's input information or user's preference information. Then, based on the sequence order n (1<=n<=N, an integer) of each search content in the search content sequence, display location information for each search content is generated. Among them, the display location information in the above-mentioned each display location information includes a horizontal coordinate X, a vertical coordinate Y, and a depth coordinate Z. The horizontal coordinate X represents the horizontal order relative to the camera position. The vertical coordinate Y represents the longitudinal order of a column corresponding to the horizontal coordinate X. The depth coordinate Z represents the depth order relative to the camera position. Therefore, the display location information of each search content can be determined according to the popularity order of each search content. The display location information includes the horizontal coordinate X, the vertical coordinate Y, and the depth coordinate Z, which can indicate that the display location information is three-dimensional. Then, according to the horizontal coordinate X, the vertical coordinate Y and the depth coordinate Z corresponding to each search content, the search content cards corresponding to the above-mentioned each search content are displayed in the above-mentioned three-dimensional space. Among them, the search content card displays the homepage content information of the corresponding search content. According to the order in the search content sequence, the above-mentioned search content card is displayed in the three-dimensional display layer corresponding to the depth coordinate corresponding to the search content. In each three-dimensional display layer of the above-mentioned three-dimensional space, each search content corresponding to each search content card corresponding to the field of view angle area is arranged at the front end of the above-mentioned search content sequence, and the display brightness of the three-dimensional display layer farther away from the camera position is smaller than the display brightness of the three-dimensional display layer closer to the camera position. The above-mentioned search content cards have the same horizontal width. Therefore, the three-dimensional display position information can be used to display each search content in different levels in the form of cards in the three-dimensional space, and the search content with higher popularity can be displayed in the form of cards in the field of view angle area. The displayed search content cards have the same horizontal width, which can make the search content cards neatly arranged for easy viewing by the wearer.The 3D display layers closer to the camera have a higher display brightness, making it easier for the wearer to view the content displayed in the 3D display layer in front. Finally, in response to detecting a slide-to-refresh operation on each 3D display layer in the 3D space, updated search content cards are displayed in each 3D display layer. The 3D space is displayed in an AR device with a FOV range of 40-60 degrees. The value of N ranges from 11 to 55. The value of the horizontal coordinate X ranges from -5 to 5. The value of the depth coordinate Z ranges from 1 to 4. Thus, the search content cards displayed in each 3D display layer in the 3D space can be refreshed overall. Because the displayed search content cards are displayed in different 3D display layers at different distances from the camera and at different display brightnesses, the integration with the AR device's functions is enhanced, thereby improving the compatibility of the displayed search content with the AR device. Furthermore, because the displayed search content cards correspond to different depths and brightnesses, the wearer's sense of three-dimensionality and spatial perception is enhanced when viewing each search content card. As a result, the compatibility of the displayed search content with the AR device is improved, and the stereoscopic and spatial perception of the wearing user is enhanced.

[0074] 6 , which shows a process 600 of another embodiment of a method for displaying search content in a three-dimensional space. The process 600 of the method for displaying search content in a three-dimensional space includes the following steps:

[0075] Step 601: Acquire a search content sequence according to input information of a search box displayed in a corresponding three-dimensional space or preference information of a current user.

[0076] Step 602 : Generate display position information of each search content according to the sequence order n (1<=n<=N, an integer) of each search content in the search content sequence.

[0077] Step 603 : Displaying search content cards corresponding to the search content in the three-dimensional space according to the horizontal coordinate X, vertical coordinate Y, and depth coordinate Z corresponding to the search content.

[0078] Step 604 : In response to detecting a slide refresh operation on each three-dimensional display layer in the three-dimensional space, display updated search content cards in each three-dimensional display layer.

[0079] In some embodiments, the specific implementation of steps 601-604 and the technical effects brought about can refer to steps 101-104 in the embodiments corresponding to Figure 1, and will not be repeated here.

[0080] Step 605 : In response to detecting a hover operation on a search content card displayed in any three-dimensional presentation layer, the target search content card is moved out to a target layer.

[0081] In some embodiments, the execution entity (e.g., an AR device) of the three-dimensional search content display method may, in response to detecting a hover operation on a search content card displayed in any three-dimensional display layer, move a target search content card to a target layer. The hover operation may involve the anchor point remaining on the search content card for a preset duration. For example, the anchor point may be positioned on the search content card using a ray, anchored to the search content card for a preset duration using head control, or hovered over the search content card using a mouse. The target search content card is the search content card corresponding to the hover operation. The target layer may be a layer in front of the three-dimensional display layer. The target layer may be located at a smaller distance from the camera position than the distances of the three-dimensional display layers from the camera position. The target search content card displayed in the target layer may have a larger card size than the target search content card displayed in any three-dimensional display layer. For example, the target search content card displayed in the target layer may have a card size twice the card size of the target search content card displayed in any three-dimensional display layer. For image and text search content cards, the search content card displayed in the target layer can display the main image and text box at their original scale. A slider bar can also be displayed within the search content card, allowing users to scroll through the content. The search content title can be fully displayed within the search content card displayed in the target layer.

[0082] In some optional implementations of some embodiments, the execution entity may move the target search content card out to the target layer through the following steps:

[0083] The first step is to determine the card size of the target search content card in any of the three-dimensional display layers.

[0084] The second step is to determine the magnification factor of the target search content card based on the determined card size. In practice, the execution entity may determine the magnification factor as a first preset factor in response to determining that the target search content card is a video card and the ratio of the first image of the video corresponding to the target search content card is a first preset ratio. The execution entity may also determine the magnification factor as a second preset factor in response to determining that the target search content card is a video card and the ratio of the first image of the video corresponding to the target search content card is a second preset ratio. The execution entity may also determine the magnification factor as a third preset factor in response to determining that the target search content card is a graphic card. The third preset factor may be greater than the second preset factor. The second preset factor may be greater than the first preset factor. For example, the first preset factor may be 1.3. The second preset factor may be 2. The third preset factor may be 3. The first preset ratio may be 9:16. The second preset ratio may be 16:9.

[0085] In the third step, based on the magnification factor and the determined card size, the card size of the target search content card in the target layer is generated as the target card size. In practice, the execution entity may determine the target card size as the product of the magnification factor and the card size.

[0086] In the fourth step, the target search content card is moved out to the target layer and enlarged to the target card size. In this way, the target search content card can be made to present a gradually enlarging animation effect during the process of moving from the three-dimensional display layer to the target layer.

[0087] In some optional implementations of some embodiments, the execution entity may, in response to determining that any of the three-dimensional display layers is not the three-dimensional display layer closest to the camera position, move the target search content card out to the target layer. Simultaneously, for each three-dimensional display layer before any of the three-dimensional display layers, in response to determining that the target search content card has moved to the three-dimensional display layer, move each search content card adjacent to the target search content card in the three-dimensional display layer to the sides. Furthermore, in response to determining that the target search content card has moved out of the three-dimensional display layer, reset each search content card in the moved three-dimensional display layer. Thus, each search content card adjacent to the target search content card in the front three-dimensional display layer may exhibit an animation effect of moving to the sides and then resetting, thereby causing the target search content card to exhibit an animation effect of being squeezed forward.

[0088] Optionally, the above execution entity may further perform the following steps:

[0089] The first step is, in response to detecting a selection operation acting on the target search content card in the target layer, enlarging the target search content card and displaying it at the center of the target layer, and hiding the search content cards displayed in the three-dimensional display layers. The selection operation may be an operation to confirm the selection of the target search content card. For example, the selection operation may be a gesture operation. For example, the selection operation may be an operation of pinching and then separating the thumb and index finger. The center position may be the center position of the field of view area in the target layer. The target layer also displays a refresh control and a return control. The refresh control may be used to refresh the content related to the target search content card. The return control may be used to return to the previous interface status display. In this way, the subspace of the target search content card may be entered for display.

[0090] The second step is to obtain a sequence of related content corresponding to the search content corresponding to the target search content card. Here, each related content in the related content sequence can be related content whose similarity to the target search content card satisfies a preset condition. The preset condition can be a preset order of similarity ranking first. The preset order can be pre-set. The related content in the related content sequence can be arranged in descending order of information popularity.

[0091] In the third step, the related content cards corresponding to the related content sequence are displayed around the target search content card in the three-dimensional space. In practice, the execution entity may display the related content cards around the target search content card according to a pre-set subspace card display column sequence. The odd-numbered columns in the subspace card display column sequence may be arranged to the left of the target search content card. The even-numbered columns in the subspace card display column sequence may be arranged to the right of the target search content card. The arrangement of the related content sequences in the subspace card display column sequence can refer to steps 102-103 in the corresponding embodiments of FIG. 1 and will not be further described here. Optionally, after determining the depth coordinates of the related content cards, the depth coordinates of the related content cards in the three-dimensional display layers subsequent to the first three-dimensional display layer may be randomly assigned to 1. This allows more related content cards to be preferentially displayed in the preceding layers. For example, the depth coordinates of one-third of the related content cards in the second three-dimensional display layer may be randomly assigned to 1. The depth coordinates of two-thirds of the related content cards in the third three-dimensional display layer may also be randomly assigned to 1.

[0092] As an example, a schematic diagram of arranging related content cards can refer to Figure 7. In Figure 7, the subspace card display column sequence can be divided into 11 columns. The column on the left side close to the middle position is the first column. The left side of the target search content card 701 is the odd-numbered column, and the right side is the even-numbered column. There are 39 related content cards in total. The smaller the serial number, the higher the information popularity. Related content cards with smaller serial numbers are arranged in the middle position first. The related content cards in the first column are arranged from top to bottom from the field of view angle area, and the first related content card is aligned with the top edge of the field of view angle area. The related content cards in the second column are arranged from bottom to top from the field of view angle area, and the last related content card is aligned with the top edge of the field of view angle area. The related content cards in the third column are arranged from top to bottom from the field of view angle area, and the last related content card is aligned with the bottom edge of the field of view angle area. The related content cards are divided into three different three-dimensional display layers.

[0093] In some optional implementations of some embodiments, the execution entity may enlarge the target search content card and display it at the center of the target layer through the following steps:

[0094] In the first step, in response to determining that the content type corresponding to the target search content card is graphic or text, the target search content card is magnified to a target magnification corresponding to the viewing angle area. The target magnification can be a magnification such that the magnified target search content card substantially fills the viewing angle area. For example, the target magnification can be 3.5 times. This makes it easier for the user to read the text.

[0095] The second step is to display the enlarged target search content card at the center of the above target layer.

[0096] In the third step, in response to detecting a content sliding operation on the target search content card, the display content corresponding to the content sliding operation is displayed on the target search content card, thereby allowing the user to slide and view graphic content and text content.

[0097] As can be seen from Figure 6, compared to the description of some embodiments corresponding to Figure 1, process 600 of the method for displaying search content in a three-dimensional space in some embodiments corresponding to Figure 6 embodies expanded steps after hovering a search content card. Thus, the solutions described in these embodiments can move the hovered search content card to a target layer closer to the user for enlarged display, making it easier for the user to view in detail.

[0098] 8, which shows a schematic diagram of the structure of an AR device 800 suitable for implementing some embodiments of the present disclosure. The AR device shown in FIG8 is merely an example and should not limit the functions and scope of use of the embodiments of the present disclosure.

[0099] As shown in FIG8 , the AR device 800 may include a processing device 801 (e.g., a central processing unit, a graphics processing unit, etc.), which can perform various appropriate actions and processes according to a program stored in a read-only memory (ROM) 802 or a program loaded from a storage device 808 into a random access memory (RAM) 803. Various programs and data required for the operation of the AR device 800 are also stored in the RAM 803. The processing device 801, the ROM 802, and the RAM 803 are connected to each other via a bus 804. An input / output (I / O) interface 805 is also connected to the bus 804.

[0100] Typically, the following devices can be connected to the I / O interface 805: an input device 806 including, for example, a touch screen, a touchpad, a keyboard, a mouse, a camera, a microphone, an accelerometer, a gyroscope, etc.; an output device 807 including, for example, a micro display screen, a speaker, a vibrator, etc.; and a communication device 809. The micro display screen is used to cooperate with the optical elements to form an image in front of the user's eyes. The communication device 809 can allow the AR device 800 to communicate with other devices wirelessly or by wire to exchange data. Although Figure 8 shows an AR device 800 with various devices, it should be understood that it is not required to implement or have all the devices shown. More or fewer devices may be implemented or have alternatively. Each box shown in Figure 8 may represent one device, or may represent multiple devices as needed.

[0101] In particular, according to some embodiments of the present disclosure, the processes described above with reference to the flowcharts can be implemented as computer software programs.

In some embodiments of the present disclosure, the computer-readable signal medium may include a data signal propagated in baseband or as part of a carrier wave, which carries computer-readable program code. Such a propagated data signal may take a variety of forms, including but not limited to electromagnetic signals, optical signals, or any suitable combination of the above. A computer-readable signal medium may also be any computer-readable medium other than a computer-readable storage medium that can transmit, propagate, or transport a program for use by or in conjunction with an instruction execution system, apparatus, or device. The program code contained on the computer-readable medium may be transmitted using any suitable medium, including but not limited to wires, optical cables, RF (radio frequency), etc., or any suitable combination thereof.
